Windows Malicious Software Removal Tool x64 - November 2019 (KB890830) keeps updating over and over and over, etc. etc. etc.
So far, when I ask for updates, this one has downloaded and installed 7 times just today. I go nuts over security things that don't work properly.

Many reports on the Feedback Hub already, so I imagine they will address this sooner or later.

If its bothering you, you could temporarily / permanently disable the MRT tool being offered via Windows Update Service, by modifying your Registry:
  • Type cmd into Cortana Search field, then press Ctrl + Shift + Enter keys together
  • Click yes when UAC prompts you
  • Now in the elevated command prompt type the following commands:

    Code:
    reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MRT


    Press Enter, then type the following:

    Code:
    reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MRT /v "DontOfferThroughWUAU" /t REG_DWORD /d 1


    Press Enter then type exit and press Enter again to close the elevated command prompt.


  • Now just restart computer, for changes to take affect.


    To reverse this modification:

    Either type the following to remove the MRT key completely:

    Code:
    reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MRT /f


    or type the following to remove the DWORD value:

    Code:
    reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MRT /v "DontOfferThroughWUAU" /f


    or type the following to modify the DWORD value to 0 ( disabling it, and thus allow Microsoft to offer MRT via WU service):

    Code:
    reg add HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MRT /v "DontOfferThroughWUAU" /t REG_DWORD /d 0

    Again, you'll need to restart computer for these changes to take affect.
